To wZl whom, it may cmwern:

Be it known that I, 'WILLIAM H. MCAN- DREWS, a citizen of the United States, residing at Bradford, in the County of McKean and State of Pennsylvania, have invented certain new and useful Improvements in \Vater-Closets; and I do hereby declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the acconpanying drawings,which form part of this speeification.

My invention relates to improvements in water-closets which connect with scwers or other ontlets.

The object of my invention is to provide a water-closet with valved connections and water seals, which will dispense with the ordinary S-trap, and at the same time effeetually prevent the escape of gases from the sewer into the apartment.

My invention consists in providing an unobstructed channel or duet from the seat of the closet to the sewer when in use, and in injecting sireams of water into said duet or channel in such a manner as to form a seal or pocket to prevent the upward passage of gas or foul air, while at the same time the eXerement is free to pass into the sewer.

My invention consists, further, in providing the duet or channel with two or more pantraps, which are adapted to close the basins of the main channel when the water-closet is not in use, said pans being adapted to be automatically filled with water, so as to form a water seal, and prevent the gases from rising from the sewer into the apartment when the 'closet is not in use.

My invention consists, further, in certain details of Construction, which will be more fnlly set forth hereinafter, and pointed out in the claims.

Referrng to the drawings, Figure 1 is a vertical sectional view of my improved closet. Fig. 2 is a top or horizontal sectional view with the seat removed. Fig. 3 is a top view, showing the water seal formed by the inward spraying of water. Fig. et is a vertical sectional view of the upper portion of the closet and valved conneetions with the seat elevated.

M is the shell or cone-shaped cylinder, which forms the duet or main channel from the seat and upper bowl to the pipe a, which connecis directly with the Sewer. The shell or coneshaped cylinder M is provided with an external water-chamber, A,whch extends entirely around the same and eonnects with the interior of the shell by means of a series of perforations, a, the ofiice of which will be more fully hereinafter described. The upper portion of the shell or cylinder M :is also provided with a water-chamber, Z, which extends part way round and eonnects with the bowl of the closet by means of an aperture, r, near the bottom of said chamber, and also by means of a series of perforations, e', near the top thereof, the functions of which will more fully be described.

To the inward projecting and downturned upper end of the shell M is Secured the basin B, the outer walls of which form the inside wall of the chamber l,and,as before intimated, eonnects with said chamber by means of an opening, r, said opening being closed when the seat of the closet is depressed by means of a sliding valve, d, which is connected to the seat v bers A and l are connected to the water-supply pipe Ic in any suitable manner, and are provided with stopcocks r h, which are connected to a vertical rod, f, said rod f being connected to the seat E in such a manner that by depressing the seat the water will be turned on, and by raising the seat the water will be turned off. The tilting pans which form the water seal for the basin B and cone C are pivoted in any suitable manner to the shell M, and are also connected to and operated by the rod f, so that when the closet is in 'use and the V seat depressed the pans will be removed from the mouth of the basin B and cone C, and permit allmatter to readily fall into the sewer- IOO - form a seal to pipe, while at the same time the water will be turned into the chainbers A Z, The water' entering the chamber'A under pressure escapes through the perforations a in horizontal jets into the interior of the shell M, which, by striking against each other and the opposite walls of the shell, for-nis a spray-strap, through which liquids and solids will readily pass downward, but prevents the upward passage 'of the gases More than one row ofperforations may be made in the walls of the chambe's A Z to form a more compact and solid spray seal, but one row is sufficient for ordi'-: nary purposes.

As before statedwhen the seat is depressed, the water is turned into the chambers A and Z,the slide-valvedis forced overthe 'opening r and allows the water to accunulate in the chambe r Z until it reaches the: perforations a formedinthe' upperportion of the basinB, when itis forced therethrough and escapes do wn the sides oi' the bowl, removing therefron' the excrement, pap-`er,-or other aecumlated matter; The seat is hin ged' at the back part, and i's prov ikled with a series of springs, `q whichserwe' to holdthe front edge or side ot" it man el-evated position, so that'when the weight of the operator is renove'dtherefrom the Valve d w ill be r aised and the water which has accum'u'lated in -the chamberl'pernitted -to escapezinto the pans' or traps below and thus prevent the escape of gas 'from thesewern r In order that the Valve g may be opened by the descent ol' the rod f an instantin advance ofthedownward movement of the seal-pansc b, i[connect the rods i and j -of the pans to the rodifiby neans 'of 'a slotted connection, or in any other suitable man ner, -so that =the spray seal w i ll be formed before the pau c is removed from the cone C,th`u`smakingit impossible for the gas to escape during the periods-of change.

l do not limit myselifto a single spray' seal withii the main duet or channel, as-it is obviou's th'at any number may be used without departing from the spirit of my inventioni &Having thus described-my invention, what I el' "im, and desire to secure by Letters Patent, i i r 1' l; 1: A water-closet provided with a waterchamber in its upper portion, which comnu circling the main shell oreone-shaped cylinder M,and communicating with the interior thereot' by a series ofholes or perl'orations, in com- 1 bination With a suitable water-supply, as described, whereby a spray seal is forned in the `closet and the gases prevented fron rising while the closet is in use, as set forth.

3. In a water-closet, the perforated waterchamber A, comiunicating with a suitable water-supply,*i-n combination with the Funnel or contract-ed portion '0,' as set forth'y'aidfor the-purpose described. i

4; A water-closet' provided with inovable Watertraps; adapted to be openedwhen -the seat -is depressed to admitot' thefree downward passage of extraneous 1'nat`ter, `in' combi= nation with-'a water spray sealto close the main channel of the closet and arrest the Upward flow of gas from the sewer, as-set forthi i 5. A water-cl oset provided withpivoted pans or bowls which are'tlted'wheh the closet is in use 'to form a free and'unobstructed'passage for extraneous matter, said pa-ns" being elevated into a horizontal position 'and automatically filled with water to forma's'ealor trap' by'the upward movementof-the; seat when l'ree from the weight' of the' stter, als-'set f ithi f.
